Not sure what it is Jim, other than a person with his/her head up a pipe. Looks a bit like the installations they did at the art school I went to. The man walking is a good touch. Nice one, a bit odd but good to see. Can you expand on why? Maybe it's a periscope?
Interesting.
Haha, I knew this pic would prompt more questions.
This was in Hyper Japan (HYPER JAPAN 2013: The UK) today. The dude was in a strange costume with a long pipe stuck on his head, standing in the corner acting even more strangely...
